This metallic assembly accommodates angular and parallel misalignment while damping torsional vibration in high-speed, high-torque applications. Typically installed between an accessory gearbox and driven equipment such as pumps, alternators, or hydraulic motors.

The coupling maintains power transmission reliability during normal flight operations and ground service. Installation should follow the Aircraft Maintenance Manual for your aircraft type and verify part eligibility in the Illustrated Parts Catalog.
