A planar coupling having a first coupling plate connected drivably to a torque input member and a second coupling plate connected to a torque output member, the first coupling plate being mounted for rotation relative to the second coupling plate, the first plate having angularly spaced recesses at uniform radial distances from the axis of the assembly, the second coupling plate having cooperating recesses in which are positioned force transmitting struts that are biased in an axial direction relative to the axis of the assembly so that upon relative rotation of the coupling plates, the struts in the second coupling plate will engage the recesses in the first coupling plate, the geometry of the struts providing for simplified manufacture and for reduced stresses in the struts as they engage the coupling plate recesses.

[ Having described preferred embodiments of the invention, what is claimed and desired to be secured by U.S. Letters Patent is:] [1.] A planar overrunning coupling having a driving coupling plate and a driven coupling plate on a common axis, said plates being connected, respectively, to a rotary torque input member and to a rotary torque output member, each plate having coupling face, said coupling faces being in close juxtaposed relationship, one with respect to the other, each coupling face being in a plane that is perpendicular to the common axis;strut recesses in each of said coupling faces at locations spaced angularly about said axis at generally equidistant radial locations relative to the axis;force transmitting planar struts, a first edge of each strut being received in and pivotally engageable with a strut recess in one coupling plate and a second edge of each strut being engageable with a recess in the other coupling plate;said second edge of each strut having a first curvature and the strut recesses in said other coupling plate having a wall with a second curvature. The radius of the second curvature being equal to or greater than the radius of the first curvature of said strut edges whereby loads transferred through said struts are distributed over a load bearing surface to reduce stress during transfer of torque from said torque input member to said torque output member.
