A machine for transferring metered quantities of flowable materials, such as yoghurt, between a source and successive receptacles on a conveyor has a housing with an inlet in register with the source and an outlet in register with successive empty receptacles on the conveyor, and a metering device which is rotatably mounted in the housing and has an internal chamber as well as an opening which communicates with the chamber and registers with the inlet in a first angular position of the metering device and with the outlet in a second angular position of the metering device. The opening is provided in or close to one end portion of the metering device and the other end portion of the metering device extends from the housing and can be indexed between the first and second positions by a mechanism including a driving unit and a torque transmitting sleeve between the driving unit and the other end portion of the metering device. The sleeve is fastened to the metering device, either directly by way of screws or similar fasteners, or indirectly by way of a tubular insert which surrounds a bearing for the piston rod of a piston reciprocable in the chamber of the metering device to draw flowable material into the chamber in the first position and to expel flowable material from the chamber in the second position of the metering device.
