An electrically-actuated variable camshaft timing (VCT) assembly including an electric motor for controlling the VCT assembly having a rotor and a motor output shaft; a gearbox assembly having an input coupled to the motor output shaft and an output configured to be coupled with a camshaft of an internal combustion engine; and a torque-limiting assembly coupled to the motor output shaft that prevents angular displacement of the motor output shaft relative to the rotor and includes a spring that releasably engages the rotor to the motor output shaft to prevent angular displacement of the rotor relative to the motor output shaft at or below a torque limit and permits angular displacement of the rotor relative to the motor output shaft above the torque limit.
