Actuating device and lock device

An actuating device for a lock device, the actuating device comprising:

• an actuating element manually rotatable about an actuating axis;
• an electric generator arranged to be driven by manual rotation of the actuating element about the actuating axis;
• and
• an electromechanical coupling device arranged to be electrically powered by the electric generator, the coupling device being configured to adopt a decoupled state, for decoupling the actuating element from a locking member, and a coupled state, for coupling the actuating element to the locking member;
• wherein the coupling device comprises a blocker, a holder and a release mechanism;
• wherein the holder is arranged to adopt a holding position, in which the holder holds the blocker, when the coupling device adopts the coupled state;
• wherein the holder is arranged to adopt a released position, in which the holder does not hold the blocker, when the coupling device adopts the decoupled state;
• and
• wherein the release mechanism is arranged to mechanically force the holder from the holding position to the released position by manual rotation of the actuating element about the actuating axis.
