The Wynne corrector has a flange at its camera end which seats onto the AAF3 adapter. This flange is about 2mm thick. The camera adapter should have a matching flange approximately 1.5mm thick, so that when it is bolted to the Wynne, the total flange thickness is 3.5mm.
The three grubscrews, which have tapered ends, then grip the corrector/adapter assembly firmly by engaging the flange with their tapered ends. The points of the screws should not engage the corrector/adapter barrel.
When set up like this, it is quite easy to rotate the camera/Wynne assembly by slightly loosening the grubscrews - NOT TOO MUCH! - rotating the camera, then retightening the grubscrews.
I have found this is easier than fiddling with the red wheel - and more accurate.
Judging by your photos, your camera adapter will need modification to achieve such a set-up.
Hope this helps.
