The setting drive has a housing (10) containing a setting shaft (18) carrying a transmission wheel (22), and a return spring (25) between the housing and the shaft. The setting shaft is driven by an electric servomotor. The return spring has one end (251) fixed to the transmission wheel and the other end (252) to a holding pin (27), which is initially fixed to the transmission wheel, and is subsequently released from fixing to the wheel in the housing. |
