Re: Sprocket adapters....
There used to be tape called 'friction tape'.
My old man (way back in the 60s) used it all the time. It was like a rough fabric with tack to it, sticky.
You know, you might try a can of plasti-dip spray-on rubber stuff.
I used it to keep my tensioner and gas tank from moving around and it has worked fine.
Rough up the hub with emery cloth, spray a light coat on it, then spray a light coat inside the adapter.
When they have dried install the adapter and see if there is a small gap between the two parts. If the screws tighten down and there is no gap between the two halves, it would mean the thing might still slip.
Good luck to you.
