    摘要: The invention relates to a coupling device between a shaft (14) and a pulley (11) as well as to an engine block suitable for being installed in a motor vehicle. The shaft (14) and a pulley (11) can rotate relative to one another about an axis (15). According to the invention, the device includes a separate declutchable means (36, 37, 40, 42, 45, 50) for driving the shaft (14) by the pulley (11) only allowing the shaft (14) to be driven by the pulley (11) when the latter is rotating at a rotation speed that is higher than a predetermined rotation speed. The engine block includes a heat engine, a reversible alternator for starting the heat engine and generating electric power, an accessory, the heat engine and the reversible alternator being suitable for rotating the accessory by means of a belt. The engine block includes a coupling device according to the invention between an output shaft (14) of the heat engine and a pulley (11) driven by the belt (10).
