A decoupler that includes a hub, a drive member and a one-way clutch and torsionally resilient coupling. The drive member is configured to engage an endless power transmitting element. The one-way clutch and torsionally resilient coupling is disposed in series in a torque path and has a carrier and a wrap spring. The carrier defines a groove. The wrap spring is formed of wire and has an engagement end and a plurality of helical coils. The engagement end is being shorter in overall length than a length of one of the helical coils. The engagement end is received in the groove. The carrier is received in a pocket formed in a rotary member that can be the hub, the drive member, or a component in a torque path between the hub and the drive member. An axial end face of the wire that forms the wrap spring is abutted against an edge of the pocket.
