Chris, I just had a look at mine from QHY.
The only thread is a M42 (or T2) female thread. The ring attaches to the camera with 3 thumb screws to the M48 dovetail.

Below is a cut/paste from the QHY12 manual.

There is a M42/0.75 thread on the QHY10/12, which can connect directly to the telescope.

If it needs adjustment, then the center and angle adjustment ring should be used.

Center adjustment---- unscrew the three screws around the ring. The adjustment ring sets into
the dovetail slot of QHY10/12. By adjusting the location of the three screws, you can achieve about
1mm center adjustment.

Angle adjustment-----slightly unscrew the three screws. There is small screw on the slide side of the
ring, which adjusts the size of inclination angle. If you rotate QHY10/12 relative to the adjustment ring, you
can obtain the correct angle.

After finishing the adjustment you should lock up the three screws.

I added a photo of mine.
