  "textContent": "A shaft for a gas turbine engine is provided that includes a first shaft section (106), a second shaft section (108), a first flexible linkage (110), and a second flexible linkage (112). The first shaft section (106) extends between a forward axial end (114) and an aft axial end (118) along a first axial centerline (194). The second shaft section (108) extends between a forward axial end (116) and an aft axial end (120) along a second axial centerline (196). The first flexible linkage (110) includes a bridge section (140) connected between a first diaphragm (136) and a second diaphragm (138). The first diaphragm (136) is connected to the aft axial end (118) of the first shaft section. The second diaphragm (138) is connected to the forward axial end (116) of the second shaft section. The second flexible linkage (112) includes a diaphragm (152) and a hub (154). The second flexible linkage diaphragm cantilevers radially outwardly from an inner radial end (156) to an outer radial end (158), and is connected to the aft axial end (120) of the second shaft section. The hub (154) is connected to the outer radial end (158) of the second flexible linkage diaphragm (152), and includes an engine shaft coupling (172) connected to the hub.",
