General purpose power transmission coupling, also used in motion control applications and rotational power transmissions, is good replacement for your needs.
It is designed to transmit torque while damping system vibrations and accommodating misalignment to protect other components from damage.
Jaw couplings have three parts: two metallic hubs and an elastomer insert called an element, but commonly called "".
