1. A system comprising: an adjustment joint including an inlet, an outlet, and a bore to transmit a fracturing fluid through the adjustment joint, wherein the adjustment joint is configured to be varied in length to facilitate coupling of a fracturing manifold to a fracturing tree; the adjustment joint includes a pipe connector having a first collar disposed about a first tubular member and a second collar having a flange; the first collar includes an interior, threaded surface to engage a mating surface of the second collar; the flange of the second collar is coupled to a mating flange of a second tubular member; the pipe connector is configured such that rotation of the first collar causes translation of the second collar with respect to the first collar to vary the length of the pipe connector; and wherein the adjustment joint comprises a first seal and a second seal in an annular space bound by the first tubular member, the second tubular member, and the second collar, and includes a test port extending from the annular space at a position between the first seal and the second seal and through the second tubular member. 2. The system of claim 1, comprising: the fracturing manifold; andthe fracturing tree coupled to the fracturing manifold to enable receipt of the fracturing fluid from the fracturing manifold. 3. The system of claim 2, wherein the fracturing manifold is mounted on at least one skid to enable movement of the fracturing manifold and includes a plurality of valves to control flow of fracturing fluid from the fracturing manifold to a plurality of fracturing trees. 4. The system of claim 3, wherein the plurality of valves includes a first valve to control flow of the fracturing fluid from the fracturing manifold to a first fracturing tree and a second valve to control flow of the fracturing fluid from the fracturing manifold to a second fracturing tree, and the adjustment joint is disposed in the fracturing manifold to enable variation in the distance between the first valve and the second valve. 5. The system of claim 2, wherein the fracturing manifold includes a valve to control flow of fracturing fluid from the fracturing manifold to the fracturing tree, and the adjustment joint is disposed between the valve and the fracturing tree to enable variation in the length of a fluid connection between the valve and the fracturing tree. 6. The system of claim 5, comprising an additional adjustment joint disposed between the valve and the fracturing tree to enable variation in the length of the fluid connection between the valve and the fracturing tree, wherein the adjustment joint and the additional adjustment joint enable variation in the length of the fluid connection in different directions from one another. 7. The system of claim 2, comprising two additional adjustment joints, wherein the adjustment joint and the two additional adjustment joints enable three translational degrees of freedom in aligning a pipe connection between the fracturing manifold and the fracturing tree. 8. The system of claim 2, wherein the fracturing tree is coupled to the fracturing manifold by a single fluid connection. 9. The system of claim 1, wherein the adjustment joint includes a fluid port that enables the length of the adjustment joint to be varied through hydraulic actuation. 10. The system of claim 1, wherein the adjustment joint includes a seal and a piston that is positioned to set the seal in response to hydraulic pressure on the piston.
