1. A dose detection module to attach to a dose actuator of a medication delivery device, the dose actuator having a cylindrical button sidewall that a user can use to set a dose, and an axial surface, the device comprising a sensed component rotatable during dose dispensing, said module comprising:
a housing;
a plurality of attachment arms configured to removably attach to the cylindrical button sidewall of the dose actuator; and
an electronics assembly contained in the housing, comprising a processor, and at least one measurement sensor operably coupled to the processor, wherein the at least one measurement sensor is configured to detect angular position and/or rotational movement of the sensed component to generate position signals, wherein the electronics assembly includes an identification sensor operably coupled to the processor, and a light guide member configured to provide an optical path for the identification sensor,
wherein, when the dose detection module is attached to the cylindrical button sidewall of the dose actuator, the identification sensor is disposed facing the axial surface of the dose actuator, the light guide member is disposed between the identification sensor and the axial surface of the dose actuator, the identification sensor configured to detect an indicia from the axial surface, the indicia being information associated with a type of the medication delivery device or a medication contained with the medication delivery device.
