Torque measurement on a ball and socket joint

I am trying to figure out a way to measure the torque on a ball and socket joint. The ball and socket joint in this case does not necessarily need to be friction-less which is why I am looking for a quantitative way to measure this value.

The issue that I am running into is that the torque is being applied around 2 axes rather than just 1, so traditional torque measuring tools would not work.

 

The movement is like making a cone. There is a fixed point at the bottom and the rod is tilted. The top of the rod can then move in a circular motion.
