1. A belt pulley decoupler configured for a motor vehicle drive train, the belt pulley decoupler comprising:
a hub constituent part configured for attachment to a crankshaft of an internal combustion engine,
a flexible drive element pulley configured to be spring-damped supported relative to the hub constituent part, and
a vibration absorber comprising a mounting plate having:
a fastening region,
a collar region extending radially outwardly from the fastening region, the collar region configured to receive at least one mass element, and
the fastening region:
attached to the hub constituent part,
having a plate portion supported axially on a flange element of the hub constituent part, and
held relative to the hub constituent part via an axially extending dome portion formed either by the mounting plate or the flange element, the axially extending dome portion configured to fix the mounting plate to the hub constituent part before the belt pulley decoupler is attached to the crankshaft of the internal combustion engine.
