In such exemplary embodiments the rotatable shaft 30 is in operative connection with the housing 5 and a dog 21 of the lock 1′, which will be described in detail later. In such exemplary embodiments, the motor 10 extends in the housing interior 64 and is in operative connection with the shaft 30. The exemplary motor 10 is selectively operative to causes rotation of the shaft 30. Such exemplary embodiments further include the battery cell 9 extending in the housing interior 64 and in at least partially surrounding relation of the motor 10. The exemplary battery cell 9 is in operative electrical connection with motor 10. Further, in such exemplary embodiments, when viewed in cross-section, a line segment 32 between at least two points 34 and 36 on the battery cell 9 passes through at least part of the motor 10. As can be appreciated, these configurations and arrangements are exemplary, and in other embodiments, other configurations and arrangements may be used without departing from the nature of the disclosure herein.
As shown in the exemplary embodiments in FIG. 1, FIG. 2 and FIG. 1a, the exemplary driving device 1 is fitted with a base 2 fixed with respect to the lock 1′, with the gear assembly 6, electric energy source 9 and driving motor 10 being seated fixedly with respect to the base.

The coupling 13 makes it possible to manually control the lock more easily by rotation of the housing 5, with no resistance from the driving motor 10. In other words, in some exemplary embodiments, the shaft 30 is rotatable without operation of the motor 10 through manual rotation of the housing 5. In such embodiments, the at least one gear 6 is movable between a first position and a second position. In the first position of the at least one gear 6, the at least one gear 6 is operative to transmit rotational motion between the motor and the shaft. In the second position of the at least one gear 6, the at least one gear 6 is not operative to transmit rotational motion between the motor and the shaft.
