  We show that when spin and orbital angular momenta are entangled by
spin-orbit coupling, this transforms a topological spin-triplet
superfluid/superconductor state, such as $^{3}$He-B, into a topological
$s^{\pm}$ state, with non-trivial gapless edge states. Similar to $^{3}$He-B,
the $s^{\pm}$ state also minimizes on-site Coulomb repulsion for weak to
moderate interactions. A topological phase transition into a $d$-wave state
occurs for sufficiently strong spin-orbit coupling.
