A divided driver device ( 5 ) for a mechanical face seal for non-rotatable assembly on a rotary component and for the transmission of a torque to a seal ring ( 2 ) held in non-rotatable manner on the driver device. The driver device ( 5 ) is divided in at least a single radial plane so as to form sections in the form of segments of a circle that are adapted to be clamped together to form a ring shape and furthermore, it is axially sub-divided into a divided retaining ring ( 14 ) for retaining the seal ring ( 2 ) and a divided mounting ring ( 16 ) for non-rotatable mounting to the rotary component. The rings ( 14, 16 ) are coupled together for rotation in common, as indicted by ( 24 ). The retaining ring ( 14 ) comprises mutually sealed sections ( 14 <SUB>1</SUB> , 14 <SUB>2</SUB>) in the form of segments of a circle which are adapted to be placed together to form a ring shape having an inner radial dimension that is greater than the nominal outer radial dimension of the rotary component concerned ( 6 ), and said sections comprise peripherally aligned end faces ( 15 <SUB>1</SUB> , 15 <SUB>2</SUB>) which are preferably in metal-to-metal contact with one another and have a surface finish for mutually sealing them.
