6 is either 6x or A6x with A6x being much more likely as there should be no reason for declarer not to play the ace.
Partner is unlikely to have 6 diamonds as he passed so it looks like one of the most likely shapes for declarer is 5-1-4-3 or 5-1-5-2 In that case we need to take our club tricks before they disappear on top hearts.
I play small club now.

To defeat the contract. Some passive action seems to be called for, 4 is unlikely to give anything away, and may even find declarer with xxx.

Should partner give attitude when we already know he has the A?

I'd expect partner to give count if he has the ace. Anyway, if declarer doesn't have A, he must have quite a lot of shape to justify his bidding, so a singleton club seems quite likely.

I'd play another club to force him, planning to win the first diamond, cash the ace of trumps, and then force him again. I think that works if he has QJ10xx xx Qxxxx x or QJ10x xx KQxxxx x, and gives him a guess if he has QJ10xx xx K10xxx x.

I've chosen that sequence of plays in case declarer has done something cunning with QJ10xx xx Kxx Axx - cashing A before the second club would allow him to make the unmakeable.

Seems obvious to continue clubs? I think partner has 65 or 62 and will win the spade ace on the first round to give partner a ruff if he continues small.

I appreciate this is an attitude position for some people with Jxx or Jxxx in the dummy. If that is the case a club to teh ace and ruffed cannot hurt either.

At the table my partner returned a club also, I wasn´t sure if the killing defence could be realistically found, but a heart return was needed to score Q before diamond discards.

Declarer had

QJ10xx
xxx
KQ109
x

This plan doesn't work as described. Dummy's J9 mean that the third club has to come from partner's side, or from dummy. We also have to cash A at some point, to prevent a crossruff.

After a club at trick two, I'd have to win the first diamond, cash A and exit a heart, hoping that declarer doesn't have J. Alternatively, I could cash A at trick two, then play a club. That loses when declarer has ducked from Axx, and also gives me a nasty guess if declarer next leads Q.

I see from Fluffy's post that none of this is relevant anyway.

Please explain.

We continue , declarer wins K, plays a diamond, we either fly the ace or declarer finesses the 10, enters hand with club ruff to discard two hearts.
(We can't actually get partner on the lead so he might even play spades at this point)

Dummy is west, our LHO, so even when declarer can set up 2 diamond discards vefore touching trumps, we have a low trump to ruff it.
