Help Request: Detached Shifter on Breezer i3

I have a Breezer i3 I've been taking the rear wheel on and off of quite frequently recently. The last time I put it back on, the last step of screwing on the shifter box wouldn't take. In other words, the shifter box is hanging by the cable and it cannot be firmly attached to the bike. I haven't noticed any damage on it or other physical differences but one possibly unusual item is that the screw on the bottom which is responsible for the tightening does not stop when turned all the way to the right; i. e., it turns continually. Does anyone have any helpful advice?

Resolved - Thanks

The problem has been resolved with the help of the Shimano technical documents. Thanks to both of you for your feedback.

EDIT: For reference, the screw which is tightened to hold the shifter onto the hub seems to have been the culprit. When I took it all the way out, the threading was full of a thin spiral of metal, which was apparently carved out of the inside of the threading in the shifter. I cleaned both out and tried the screw again. It wouldn't go in perfectly straight but is holding the shifter on tight enough to cause it to function, if somewhat erratically.
