Most adapters of the day were just between AT and PS/2, same signals with a different connector. As Tony has pointed out, the protocols used by PC and XT are different to the ones used by the AT.

There are adapters around these days that can convert XT to AT, for people wanting to use early keyboards. Going from AT to XT is a different story - I ended up buying a switchable keyboard on eBay with ridiculous shipping from the US to use with my 5150 PC.
