A torsional damping device (4) includes a first movable element (13, 14) and a second movable element (15, 16), a central hub rotationally coupled to the second element, at least one group of elastic members (25, 26) acting against rotation of the first element and second element with respect to one another, a phasing member having by two parts (32, 33) for arranging the elastic members of the at least one group of elastic members (25, 26) in series so that the elastic members (25, 26) of the at least one group deform in phase with one another, and a pendulum damper (48) rotationally connected to the phasing member. The first and second movable elements (13-14, 15-16) are coaxial and rotationally movable around an axis X. The phasing member (32, 33) is centered on the central hub by means of a pendulum support member.
