rotating multiple objects around same axis

I'm working on an object that is a set of rings set within each other that rotate. I've written a script that rotates a ring on a given axis with a variable speed which works fine.

The problem I'm running into is getting the script to work on all 3 rings at the same time when they are linked.

I'm still working on it, but I'm not sure if I need to apply the script separately to each ring and adjust the axis in each one manually, or if somehow I have to use 1 script once they're all linked to control the behavior of each element.

Any ideas?

not sure I understand your application/question . . . have you tried applying the script to the root prim only?
