Is it a screw adapter for the camera or an 2 inch eyepiece holder type connection?

Greg, the adapter is an M63 to M48 screw type. The back of the focuser (the 2" clamp adaptor) unscrew and the camera adaptor screws directly on to the focuser tube via the M63 thread. It is a very solid assembly.

There is a focuser tube rotation lock, and i suspect that might something to check next time. It was located 180 degree opposite that corner of the camera. The Nikon 48mm adaptor also has an adjustment ring with three recessed grub screws, it is possible that this could be the culprit.
BTW, the focal point for the Nikon D5300 was just past the 35 mark on the focuser bezel. I always write that sort of reference in my notebook so i can go directly to the focal point for my various cameras. I used a Bathinov mask to establish the focal point. And yes I check it each session, it just helps to be in the neighborhood so to speak.
