As confirmation yes the US and UK Yale modules are shaped differently. So far there is still no UK HomeKit module although there is in the US from Yale.
If by deadbolt we mean Europrofile locks then there are now a number of options. As already mentioned there is the Danalock v3 which is available in both Zigbee and Z-Wave and HomeKit versions. Danalock have announced a keypad but this would mean you end up with two key pads one for the Yale Night Latch and one for the Danalock.
EveHome formerly Elgato have announced a lock this like all other EveHome products will be HomeKit only. I mention it because it is a modified version of a Yale ENTR lock - https://www.yalelock.com/en/yale/com/smart-living/products/smart-door-locks/entr/
As far as I can see even though this is not sold in the UK it is sold in Europe and uses the Yale European style modules. There is also the Yale Doorman https://www.yalelock.com/en/yale/com/smart-living/products/smart-door-locks/yale-doorman/
There is also the Nuki - https://nuki.io/en/smart-lock/
With Assa Abloy having bought August Smart Locks, I had hoped this would result in some new products for Europe. It looks like this will be a very long time happening.
Hypothetically they could have used the August technology to do a Europrofile lock and to standardise the software across August and Yale products so that one keypad could unlock both a Night Latch and a Dead bolt lock.
