ABSTRACT:
A coupler acts as an interface between a torque element of a torque sensor and a shaft receiving an applied torque. A portion of the shaft is allowed to twist freely inside the element, and the coupler transfers a portion of the torsion forces in the shaft to the element. The element deforms and generates a magnetic field or other torque response corresponding to the applied torque in the shaft. The applied torque can then be determined based on a relationship between the torque in the shaft and the torque in the element. Reducing the torsion forces applied to the element allows the element to measure higher applied torques without permanently deforming.
