I'm starting with a rigged engine model and would like to use geometry nodes to drive this model. The model works by rotating the crank shaft and using a combination of parenting and constraints everything else follows.

I'd like to use GeoNodes to do some calculations, then set the rotation of the the crank object. I tried using the following GeoNodes setup, but it does not rotate the object. It just moves the mesh.

How can I set the desired rotation using GeoNodes and have it drive a rigged model?
