1. Dose control device for a handheld pen-type injectable-drug delivery device, the handheld pen-type injectable-drug delivery device comprising an elongate body with a proximal and distal extremity, a longitudinal axis extending from the proximal extremity of the elongate body to the distal extremity of the elongate body, and a rotatable dose setting wheel located at said proximal extremity, wherein said dose control device comprises:
a magnetic field producing means located at the proximal extremity of said elongate body;
one or more magnetic field sensors in communication with a data processing unit located at the elongate body; and
a clutch assembly configured to selectively move the magnetic field producing means from a first, engaged, position, to a second, disengaged, position;
wherein said clutch assembly comprises:
a cylindrical body having a longitudinal inner bore and a proximal extremity, wherein the magnetic field producing means is located within said bore of said cylindrical body, said cylindrical body being removably mounted in axial longitudinal alignment around said rotatable dose setting wheel with an annular wall extending within and along said bore towards the proximal extremity of the cylindrical body, wherein the cylindrical body is configured to be co-rotatable with the dose setting wheel.
