Abstract
A torque converter includes a case and a bypass clutch having a plate rotationally fixed to the case and a friction disk having a friction material configured to engage with the plate to rotationally couple the friction disk to the plate when the bypass clutch is engaged. The friction disk includes a first circumferential connection surface having a plurality of alternating convex and concave arcuate segments. A drive plate includes a second circumferential connection surface having a plurality of alternating convex and concave arcuate segments. The first and second connection surfaces are in meshing engagement with the convex segments of the friction disk meshing with the concave segments of the drive plate and with the concave segments of the friction disk meshing with the convex segments of the drive plate.
