Abstract: Drilling template include a generally planar member comprising at least one mechanism for guiding a drill. The at least one mechanism is structured and arranged to align a drilling machine having the drill. The generally planar member has at least two layers which can more with respect to each other. The drilling template is capable of assuming at least one configuration when the at least two layers are prevented from moving with respect to each other. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: The invention relates to a motor-driven screw driver comprising a drive motor to which a first torque limiter is assigned and a head (1) which presents the screw-driving tool or a recess for a screw-driving tool. A ratchet mechanism (6) and a torque limiter (5) assigned to said ratchet mechanism (6) are positioned in the head (1) in such a way that the screw driver forms a manually actuated torque wrench whose torque is defined by the torque limiter (5).
