Abstract
An isolating torque coupler includes a drive element assembled between annular cage elements of a driven element. The cage elements each include a plurality of aligned voids. The drive element includes a hub portion and a plurality of lobes with each of the lobes including a first edge and a second edge. Openings in the drive element are aligned with the voids of the cage elements to accommodate isolator springs. Each isolator spring is a helical coil compression spring having squared ends. A first edge of each of the lobes of the drive element is parallel to a second end of the corresponding one of the voids of the driven element. A second edge of each of the lobes of the drive element is non-parallel to a first end of the corresponding one of the voids of the driven element.
