Pretty much. I've never actually tried to take one of these flywheels
apart to see what the dampers look like, so I'm not sure that the
mechanism looks like it does on the clutch disc. In this system, the
clutch disc is solid-- the fibers are attached to the disc, which is part
now essentially part of the hub, rather than being attached via the
dampers (the circumferential spring assemblies). The flywheel has two
parts, joined by a damper, and it's possible to turn the transmission side
of the flywheel about 20 degrees or so with respect to the engine side.
