An airfoil surface control system includes a movable surface. An actuator, 28, is coupled to the surface. The airfoil surface control system includes a motor, 22. A torque tube assembly, 26, operatively couples the motor, 22, and actuator, 28, and includes first and second shafts, 30, 32, coupled by a universal joint. The universal joint, 36, is configured to provide a first maximum angle between the first and second shafts, 30, 32. A stop is configured to provide a second maximum angle between the first and second shafts, 30, 32, that is less than the first maximum angle. |
