The drive mechanism may be axially arranged on a drillstring or pipe, compact, capable of fine control and delivering high torque or the like and may be electrically and/or hydraulically powered. The drive mechanism may comprising a driving member comprising a plurality of drivers linearly translatable with respect to the driving member, each driving member having at their ends a male engaging portion and an associated driven member, comprising a plurality of female receiving portions adapted to receive a male engaging portion, the arrangement being such that linear translation of a driver causes its engaging portion to engage with a female receiving portion and the action of the engaging portion produces a reaction in the receiving portion causing displacement of the driven member in a direction other than that of the translatable driver.
