1. A torque-limiting torsion gimbal for connecting an electric motor to a camshaft phaser, comprising:
an elongated body configured to extend from an end of a motor shaft of the electric motor to an input of a planetary gear assembly of the camshaft phaser;
an angular-displacement-resistant end of the elongated body configured to engage an end of the motor shaft; and
a key, positioned at another end of the elongated body opposite to the angular-displacement-resistant end, and configured to engage the input of the planetary gear assembly of the camshaft phaser to transmit torque from the electric motor to the planetary gear assembly, wherein the elongated body prevents an angular displacement of the motor shaft relative to the input of the planetary gear assembly and permits the angular displacement of the motor shaft relative to the input of the planetary gear assembly when a mechanical stop of the camshaft phaser is engaged.
