Zusammenfassung:	A turbine bucket including an integral rotation controlling feature is disclosed. In one embodiment, a turbine bucket includes: a blade section having an inner radial end and an outer radial end; an integral cover section connected to the outer radial end of the blade section; and a base section for engaging a rotor body, the base section connected to the inner radial end, wherein the base section includes: a central body; a set of tangs extending axially from the central body; a set of flanges radially inboard of the set of tangs and extending axially from the central body; and an integral rotation controlling feature extending from the central body, wherein the rotation controlling feature engages a radial opening in the rotor body. The integral rotation controlling feature is sized to limit rotation of the base section, when the turbine bucket is engaged with a rotor body.
