A compliant constant velocity constant torque universal joint to transmit a rotary movement between two angled shafts, and/or a kinematic pair with two independent rotational degrees of freedom. This compliant structure is a large deflection compliant joint and the misalignment angle can be changed through the range of from 0° to 60°. The mechanism includes at least three compliant or statically balanced compliant spatial 4R (four revolute joint) linkages connected between two shafts, each system including four compliant joint axes and three rigid or compliant link members. The joint axes in each system are mounted so that each axis intersects one other joint axis. The compliant system is symmetrical about a plane which bisects two shaft axes perpendicularly.
