The point is that when partner asks about the kings, they are saying that they know with 100% certainty that between the two hands, all the key cards are held. Since you have the ♥A, partner must know you have it already in order to know your side has all the key cards, so it will never be a surprise. While there are hands where it is right to overrule partner, the possession of the ace of trumps can never be one of those reasons in this auction. Also, if you are bidding RKC with voids randomly, then why can't opener have a void in diamonds instead of clubs?

Yes, and when you bid 5NT, you are saying that partner's response means we are not missing any aces. Therefore, North knows that you know he has it.

But it is your North that you want to make the decision and they do not know about the club void absent coughing, foot tapping or some related system.

The hand above was a much different situation though. From the previous bidding, I know partner must have at least Qxxxx in spades and Axxx in clubs for the 5NT bid. Those alone give reasonable play for 7C while 7S is considerably worse, and it should have more for the grand slam try. I probably should have just bid 7C over 5NT, but felt that the GIB might have been converted to 7S too often. Note that in the hand above, you need the diamond finesse playing in 7S, but not in clubs if they had broken 3-2 (diamond ruff is profitable playing in 7C). The surprise in the south hand here isn't some ace that I had already shown when I bid 5D, it was the KQ9x in its second suit which I hadn't shown.
In the OP hand, North doesn't have nearly enough information about the hand to make such a decision.

Because the ♦K was not what South wanted to hear and so south signed off (don't forget North can't see South's hand). Basically, unless some really rare situation occurs (this isn't one of them), a 4NT bid as RKC denies a void. So South would therefore know that North has ♥A and ♦AK and has still decided not to bid 7, so North shouldn't either.

Something like 1D 1S 1N 2D(art GF) 2H 3H 4D would be a great auction for south, he can keycard (his partner bypassed a club control), then ask for kings and opposite the DAK and HA and 4 hearts he can easily bid a grand.
