Abstract: A one-way clutch includes a first member having multiple first recesses, and a second member having multiple second recesses that are alignable with the first recesses. Each recess includes a load-bearing surface. The clutch also includes multiple engaging elements that are engageable with the load-bearing surfaces of the recesses to effect one-way torque transfer between the first and second members. At least one of the engaging elements comprises a non-metallic, compressible material and is configured to compress upon engagement with a respective load-bearing surface of each member to inhibit relative movement of the members.
