Lock devices, systems, and methods that can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock includes an assembly of parts that includes parts having locating features that that can assist in those parts being assembled with other parts of the assembly in a single, relative orientation. Further, lost motion may be utilized to accommodate manual displacement of one or more components of the can also be displaceable, in at least certain situations, via operation of a motor. The lock can also include an internal power source capable of driving electronics used to determine handedness of a door.

A clutch module of an electronic lock includes a housing. The housing is equipped with a lock cylinder connecting member, a first meshing cog, a second meshing cog, a restoring member, a clutch, and a driving device. The lock cylinder connecting member is configured for connecting with a mechanical lock cylinder or a switch knob, and the lock cylinder connecting member is rotatable between a locking position and an unlocking position. The first meshing cog is connected to the lock cylinder connecting member. The second meshing cog is connected to the lock cylinder connecting member. The clutch is connected to restoring member, and the clutch is equipped with a damping device. The driving device is connected to the clutch, and the driving device includes a driving state and a non-driving state.
