The revolving adapter has it's own set of interlocks, and helps connect the interlocks on the camera to the back.
So yes, if the revolving adapter is not working properly with the body or the back, it can cause problems.
I have had a situation in the past where I had a problem with a revolving adapter that I was able to isolate because I was able to swap it out with another. I'm guessing that isn't your situation.
Is there any chance that the revolving adapter wasn't mounted properly in the first place? Try separating it from both the camera and the back and then reassemble it adapter to the body, and then back to the adapter.
