wind the primary and secondary together as close as possible to each other. wind them bifilar for the closest coupling

In a typical transformer the coupling is already high because the windings sit on the same magnetic core. For highest coupling the core must form a closed path for the magnetic flux and the windings must be uniformly distributed along the core. Transformers on toroidal cores are usually good, for example. As it was already mentioned, bifilar winding also helps.

Keeping everything the same, the coupling coefficient depends on the material of the core. For example an air core will have the least coefficient of coupling
