I once successfully glued a broken nut, and it lasted another two years.
Luckily I managed not to let the glue glue it to the thread.

jkn submitted this idea :
OK, I now learn that they are called 'shade rings', or 'lamp rings'. So
at least I can get hold of some.

Still interested in a decent 'shade ring tool' or ideas for easing the
turning...

I don't know if this might help, but they used to sell a spring steel clip
to replace shade rings, stamped out of sheet metal. You just squeezed its
arms and it released the shade.

Another variation used a thin metal spring arms, which you held together
to remove the shade, but the shade needed to have a larger than normal
hole for the squeezed together arms to be able to pass through. It would
be held in place by a normal shade ring.
