Hi Paul, It seems so, I didn't realize this until you posted this comment as I'd never really tried it. The only difference between a screw lens + Adaptor K and a K- mount lens is the fact that the aperture/comms pins remain open circuit. Shorting to ground any of the proud pins on the AF adaptor will cause allow the AF to become active. I did creat a temporary solution by wedging some aluminium foil in the gap. The problem is that it's not easy to fix a contact in there without modifying each lens quite a bit as there is no way to add anthing to the Adaptor K without adding to the film flange distance.
