In a preferred embodiment a friction bushing is configured to rotate a shaft with resistance having a housing with a bore to receive the shaft; a flange plate positioned on the housing around the bore; and a number of flanges that protrude axially from the flange plate to receive the shaft, where the flanges generate a radially-directed force by being flexible from a relaxed radius to a shaft radius of the shaft, and the flanges have internal circumferentially spaced surfaces in contact with an external surface of the shaft having a topology to control the resistance as the shaft rotates in the friction bushing.
