The rotor stage includes a bladed rotor. The annular shroud assembly is disposed radially outside of the bladed rotor, and extends circumferentially around the bladed rotor, and is coupled with a turbine support case. The annular shroud assembly includes a shroud, a shroud segment housing, a cover, and a plurality of shroud pins. The shroud includes a plurality of shroud segments that collectively form the shroud. Each shroud segment includes a ring portion, a forward leg, and an aft leg. The shroud pins are disposed to connect the shroud to the shroud segment housing and the cover. The shroud segment housing and the turbine support case are engaged with one another and are configured to permit relative movement therebetween.
