The present disclosure relates to a dose detection system for use with a medication delivery device in which a dose setting member rotates relative to an actuator during dose delivery. The dose detection system comprises a module including a rotation sensor attached to the actuator during dose delivery. A sensed element is attached to the dose setting member and includes first gear teeth. The rotation sensor comprises a driven gear including second gear teeth. The second gear teeth are operatively received by the first gear teeth and are driven in rotation as the first gear teeth rotate during dose delivery. The rotation sensor is responsive to the rotation of the second gear teeth to detect the rotation of the dose setting member.
