15. A driving tool comprising:
a drive body comprising a first cam body;
a driven body comprising a second cam body; and
a rotational movement limiting subassembly comprising an elastic member, wherein the elastic member is operably coupled to the first cam body and the second cam body to affect rotational movement of the drive body relative to the driven body along a longitudinal axis of the driving tool;
wherein the elastic member is configured to permit a transfer of rotation from the drive body to the driven body such that the drive body and the drive body rotate together when a torque applied to the drive body is less than a preset amount;
wherein the elastic member is configured to inhibit the transfer of rotation from the drive body to the driven body such that the driven body does not rotate with the drive body when the torque applied to the drive body is equal to or greater than the preset amount;
wherein the rotational movement limiting subassembly comprises a first radial member;
wherein the first radial member defines a wedge channel;
wherein the first radial member is part of the rotation limiting subassembly and defines cam surfaces proximate to the wedge channel, the cam surfaces interfacing with the first and second cam bodies to transfer torque from the first body to the second cam body via the cam surfaces.
