A driver accessory includes a housing having a first housing portion and a second housing portion movable relative to the first housing portion, an input shaft at least partially received in the first housing portion and defining a first axis, and an output shaft at least partially received in the second housing portion and defining a second axis. The output shaft is supportable by the housing in a first position relative to the input shaft in which the first and second axes are substantially parallel, and in a second position relative to the input shaft in which the first and second axes are non-parallel. The driver accessory also includes a locking mechanism operable to secure the second housing portion relative to the first housing portion when the output shaft is in the first position and the second position relative to the input shaft.
