  Current-driven reconnection is investigated as a possible mechanism for
angular momentum transport in astrophysical disks. A theoretical and
computational study of angular momentum transport from current-driven
magnetohydrodynamic instabilities is performed. It is found that both a single
resistive tearing instability and an ideal instability can transport momentum
in the presence of azimuthal Keplerian flow. The structure of the Maxwell
stress is examined for a single mode through analytic quasilinear theory and
computation. Full nonlinear multiple mode computation shows that a global
Maxwell stress causes significant momentum transport.
