Abstract

A valved-container inhaler (150) has a mechanical return assembly with a spring (214) and a transfer (212) configured to transfer stored potential energy from the spring to a canister (51) and a clutch (208, 210) in a load path of the force between the spring and the transfer, the clutch being rotatable between a first condition in which load is transferred from the spring to the transfer, and a second condition in which the spring and the transfer can move relative to one another to interrupt the load path and thereby allow the canister to resile after actuation.
