A vaned element of a fluid coupler such as a torque converter includes vanes having a depression extending from a leading surface area to a trailing edge of the vane. The depression avoids multiple surface layer changes which introduce turbulence to flow of fluid past the vane. The depression also forms reinforcing ribs in the form of raised walls which dimensionally stabilize the mounting tabs for the vane. In addition the vane construction is light weight since it permits the use of simple cross-sectionally shaped vanes while improving the speed capability of the torque converter and the strength of the vaned elements. The blade construction permits automated assembly techniques for the vaned elements.
