1. A method of connecting plates in a torque converter with a rivet, the torque converter including a front cover and first and second plates and the rivet including a body, a head, and a longitudinal axis passing through the body and the head, comprising: forming the head of the rivet: such that an end surface of the head forms a convex curve; or,such that an end surface of the head forms a concave curve; or,to include a first planar portion and an end surface of the head formed by a second portion protruding from the first portion;forming a first portion of an interior surface of the cover to: when the end surface of the head forms a convex curve, indent with respect to a surrounding portion of the interior surface; or,when the end surface of the head forms a concave curve, protrude with respect to a surrounding portion of the interior surface; or,when the end surface of the head includes the second portion protruding from the first portion, be planar with respect to a surrounding portion of the interior surface;when the first portion of the interior surface of the cover indents with respect to a surrounding portion of the interior surface, forming the surrounding portion of the interior surface so that the surrounding portion does not protrude from the interior surface;disposing the body of the rivet in respective holes in respective portions of the first and second plates such that the end surface of the rivet head faces the front cover;displacing the first and second plates such that: the end surface of the head forming a convex curve contacts the first portion of the interior surface indented with respect to the surrounding portion of the interior surface; or,the end surface of the head forming a concave curve contacts the first portion of the interior surface protruding with respect to the surrounding portion of the interior surface; or,the end surface formed by the second portion contacts the first portion of the interior surface planar with respect to the surrounding portion of the interior surface; and,displacing the first and second plates such that the respective portions of the first and second plates are at an acute angle with respect to the surrounding portion of the interior surface, and the longitudinal axis of the rivet is at an acute angle with respect to a line orthogonal to the surrounding portion of the interior surface. 2. The method of claim 1 wherein: the respective holes include respective longitudinal axes; and,disposing the body of the rivet in respective holes includes aligning the respective longitudinal axes and the longitudinal axis for the rivet, the method further comprising:sliding, while applying a force to the rivet in a direction toward the cover and parallel to the line orthogonal to the surrounding portion of the interior surface, the end surface of the head of the rivet along the portion of the interior surface. 3. The method of claim 1 wherein when the head of the rivet is formed such that the head of the rivet includes the first planar portion and the end surface formed by the second portion protruding from the first portion:the longitudinal axis passes through the end surface; and,the longitudinal axis does not pass through the first planar portion. 4. The method of claim 1 wherein: the end surface of the head of the rivet includes a portion wholly enclosed by a circumferential line with respect to the longitudinal axis for the rivet; and,the portion of the end surface contacts the portion of the interior surface. 5. A method of connecting plates in a torque converter with a rivet, the torque converter including a front cover and first and second plates and the rivet including a body, a head, and a longitudinal axis passing through the body and the head, comprising: protruding a planar surface from a surrounding portion of an interior surface of the cover so that the planar surface tapers radially inward with respect to the surrounding portion of the interior surface;disposing the body of the rivet in respective holes in respective portions of the first and second plates such that the end surface of the rivet head faces the front cover; and,bending the first and second plates such that the end surface of the rivet head contacts the planar surface, the respective portions of the first and second plates are at an acute angle with respect to the surrounding portion of the interior surface, and the longitudinal axis of the rivet is orthogonal to the planar surface. 6. The method of claim 5, wherein the rivet includes a longitude axis, the method further comprising: sliding, while applying a force to the rivet in a direction toward the cover and parallel to a line orthogonal to the surrounding portion of the interior surface, the end surface of the rivet head along the portion of the interior surface so that the longitudinal axis is at an acute angle with respect to the line orthogonal to the surrounding portion of the interior surface. 7. An assembly for a torque converter comprising: a front cover including an interior surface with a portion: indented with respect to a surrounding portion of the interior surface; or,protruding with respect to a surrounding portion of the interior surface; or,planar with respect to a surrounding portion of the interior surface;first and second plates including respective portions with respective holes; and,a rivet including a body, a head, and a longitudinal axis passing through the body, wherein: the head includes: an end surface forming a convex curve when the interior surface includes the portion of the interior surface indented with respect to the surrounding portion of the interior surface; or,an end surface forming a concave curve when the interior surface includes the portion of the interior surface protruding with respect to the surrounding portion of the interior surface; or,a first planar portion and an end surface of the head formed by a second portion protruding from the first portion when the interior surface includes the portion of the interior surface planar with respect to the surrounding portion of the interior surface, wherein:the body is disposed in the respective holes;the first and second plates are deflectable to enable contact between the portion of the interior surface and the end surface of the head of the rivet as pressure is applied to compress the rivet against the portion of the interior surface to fix the rivet to the first and second plates; and, wherein:when the portion of the interior surface of the cover is indented, the surrounding portion of the interior surface does not protrude from the interior surface; and,as the rivet is compressed: the first and second plates are at an acute angle with respect to the surrounding portion of the interior surface; and,the longitudinal axis of the rivet is at an acute angle with respect to a line orthogonal to the surrounding portion of the interior surface. 8. The assembly of claim 7 wherein the first portion of the end surface is co-linear with the longitudinal axis. 9. An assembly for a torque converter comprising: a cover for driving engagement with a prime mover, the cover including a planar surface protruding from a surrounding portion of the interior surface so that the planar surface tapers radially inward with respect to the surrounding portion of the interior surface;first and second plates including respective portions with respective holes; and,a rivet including a body, a head, and a longitudinal axis passing through the body and the head, wherein: the body is disposed in the respective holes; and,the first and second plates are deflectable to enable contact between the planar surface and the rivet head as pressure is applied to fix the rivet to the first and second plates. 10. The assembly of claim 9, wherein the pressure is applied to the rivet in a direction orthogonal to the surrounding portion of the interior surface. 11. The assembly of claim 10 wherein: the rivet includes a longitudinal axis passing through the body and the head; and,the first and second plates are deflectable such that the longitudinal axis is orthogonal to the planar surface.
