I am using a Raytheon 3000 autopilot. It works great except for the
rudder sensor. My rudder will turn farther than the sensor will, causing
the threaded attachment rod to pop off.

Sounds like the arm needs to be repositioned. Where it pivots on each end
controls this. Usually there's adjustment points on each side. Whomever
installed yours did an improper job.
More likely that there is an imbalance in the actuation length of the
rudder arm and the actuation length of the Sensor. Saw the same
recently. Rudder indicator had never worked properly for 13 years!
Made a longer sensor arm now no problems.
