The invention relates to a torsional vibration damper (1) which is installed in a powertrain of a hybrid vehicle and is designed as a dual-mass flywheel and which comprises a primary section (2), a multipart secondary section (3), and a spring damping device (6) that damps torsional vibrations of the primary section (2) and/or the secondary section (3). The torsional vibration damper (1) additionally comprises a KO separating clutch (15) which is paired with an arc spring flange (9) of the secondary section (3) and comprises an actuation device (28) and a clutch disc (33) that is installed between an axially movable pressing plate (26) and the arc spring flange (9), said arc spring flange being supported against the radial inner face of the primary section (2) via a support bearing (10). The arc spring flange (9) is paired with a torque pan (20) which is aligned concentrically to the rotational axis (4) and to which an intermediate plate (23) is secured that can optionally be upgraded into a centrifugal pendulum device (24) and is in contact with the pressing plate (26) via a leaf spring (25), said pressing plate being axially movable by means of a lever spring (27) of the KO separating clutch (15).
