The prompt
Replace the rectangular forearm block with a circular output hub centered exactly on the RDS3115MG shaft axis. The hub must rotate with the servo shaft while the servo housing remains fixed. Attach a flat forearm mounting plate to the hub. Add a matching circular support around the opposite shaft. Keep both sides perfectly coaxial. No bearings or separate axle. Do not change the servo housing.
