The dispenser enables a multiplicity of doses of a substance in powder or granular form contained in a reservoir to be dispensed in succession. To form a dose a shaft must be rotated relative to a part of the dispenser, the shaft having to be substantially vertical while the dose is being formed. Between the shaft and said part of the dispenser there is provided a joint which prevents relative rotation if the shaft is not substantially vertical, or which although allowing relative rotation enables a signal to be emitted which can be sensed by the user. In particular the dispenser can be a multi-dose inhaler for medicaments.
